海洋碘循环对空气质量和大气化学有重大影响。具体而言，碘化物与海洋表面最上层几微米的臭氧反应是对流层臭氧（一种污染气体）的重要汇，也是活性碘进入大气的主要来源。目前正在空气质量模型中实施海面碘化物参数化，但这是目前不确定性的主要来源。可用于估算全球表面碘化物浓度的观测数据相对较少，迄今为止，这些数据尚未以整理的数字形式公开提供。在这里，我们提出了所有可用的海面（<20米深度）碘观测。该数据集包括从已发表的手稿数字化的值，由原始人直接提供的已发表和未发表的数据，以及从存储库获得的数据。它包含1342个数据点，跨越纬度从70°S到68°N，代表所有主要盆地。这些数据可用于模拟海面碘化物浓度或作为未来观测的参考。
The marine iodine cycle has significant impacts on air quality and atmospheric chemistry. Specifically, the reaction of iodide with ozone in the top few micrometres of the surface ocean is an important sink for tropospheric ozone (a pollutant gas) and the dominant source of reactive iodine to the atmosphere. Sea surface iodide parameterisations are now being implemented in air quality models, but these are currently a major source of uncertainty. Relatively little observational data is available to estimate the global surface iodide concentrations, and this data has not hitherto been openly available in a collated, digital form. Here we present all available sea surface (<20 m depth) iodide observations. The dataset includes values digitised from published manuscripts, published and unpublished data supplied directly by the originators, and data obtained from repositories. It contains 1342 data points, and spans latitudes from 70°S to 68°N, representing all major basins. The data may be used to model sea surface iodide concentrations or as a reference for future observations.
